Now, let’s compare this with the biological wastewater treatment process. The product is the organic load to be removed by means of wastewater treatment; the trained workers and tools are equivalent to the carrier media and biomass in the wastewater treatment process, respectively. Similar to the workers who cannot pack and ship out the products without tools, the carrier MBBR media cannot remove the organic load from the wastewater without biomass.
If one day Tom’s factory starts producing another product that requires a different packing method, he doesn’t dismiss his 11 workers and hire a new group. Rather, he allows his workers time to become familiar with their new working tools. The same applies to biological wastewater treatment: The biomass that grows on the carrier MBBR bio carrier media will gradually adapt itself to remove a different type of organic load or concentration.
In terms of treatment, a good MBBR carrier aquaculture filter media ensures that all biomass is active to remove the organic substances from the water. From the user’s perspective, a good MBBR carrier media eases the operation and provides a variety of savings, such as in construction and operation.
In a wastewater treatment application, the required amount of MBBR carrier media depends on the organic load that needs to be removed by means of the bacteria’s metabolism, the rate of which is influenced by water temperature and the type of substrate.
Although MBBR carrier media might just be a little piece of plastic (or some other material), its role in wastewater treatment is vital to keep the biomass active in order to deliver the best possible organic removal performance. WW
ill have considerable importance for optimal design and dimensioning of commercial scale RAS. It was further found that superficial air velocity is not a good scaling factor for MBBRs. Upscaling while maintaining geometry implies increasing air injection depth and therefore increased energy input will be required at a comparable superficial air velocity, which is not incorporated in the superficial air velocity term (m h−1). Superficial air velocity and plastic media filling% were found to have a strong effect on mixing time at small scale. An air velocity below a threshold of 5 m h−1 decreased TAN removal at both small and medium scale. Intense mixing at small scale increased TAN removal at low TAN concentration. However,
